As far as this specific symbol is concerned, please notice the familiar looking central portion of the figure with what appears to be our own familiar peace symbol turned upside down. According to the Plejaren, it is actually our peace symbol that is upside down, effectively creating a more martial, upraised sword-like image, the very antithesis of peace. This may help to explain why many "peace protests", with protesters carrying placards with the familiar peace symbol, often have a more agitated, militant (rather than truly peaceful) feeling about them.
The central portion of the Salome Peace Symbol, inverted from our own, is more representative of a "Tree of Life". In fact, the entire Salome Peace Symbol can be seen to convey an upward and opening energy, a more all-embracing, peaceful image. Consider what might be possible if millions of people who sincerely desire peace were resonating with a more harmonious image, and internal sense, of true peace. How much more "powerful", in a non-aggressive way, might the collective energy be for peace when people embody the energy, essence and understanding of peace?
Research done by John Diamond, M.D. has shown that, among many things, viewing certain images can have the effect of strengthening or weakening people. See: www.diamondcenter.net/.
The Salome Peace Symbol can be contemplated or meditated upon to see what it evokes within each person. There is a book with many more of the symbols, with all of the captions in German, available at www.figu.org.
